I can't really see why you're complaining. More 4 is still there (so you don't lose any programmes) and, at last, Film Four will be added to the line-up.
It was slightly irritating when Men & Motors disappeared from Freeview (because I enjoyed the re-runs of 'Minder') but, if (through low viewing figures) the broadcasters can't attract enough advertisers to make their participation in Freeview viable, it makes perfect sense that should move aside and free up channels for others to try.
